What sound transmission ratings are listed for 400 Series Stormwatch windows?

The uploaded PDF includes Standard Glass STC and OITC values for selected configurations, with several listed STC values in the 30s depending on product and glazing type.

What STC and OITC mean

STC and OITC are sound transmission ratings. Higher values generally indicate greater sound reduction, though values depend on the full tested unit and glazing configuration.

Source note

The PDF states that STC and OITC values are for individual units based on independent tests and represent the entire unit.
